I have no specific information on Nikkor lenses; however, there is no such beast as a 'universal' grease that can be applied across the whole range of a manufacturer's lenses - very small increases in helical diameter and length can turn a grease that gives a silky finger tip feel on a 85mm/f2, into a wrist breaking wrestling match on a 180mm/f2.8! You should always try and find the original lube specification and method of application. This is especially important when one is dealing with large diameter lenses or long helicals, it is then quite easy to find a modern equivalent with comparable viscosity/penetration values to start experimenting with. The actual method of application is also very important - in many original specifications you will find that very specific mixtures of greases are used. In some cases these 'mixtures' are actually blended together before application, in others the different greases are applied individually to specific areas of the helical. I have always followed the 'find the original spec' route and then looked at what is available from specialised manufacturers, or trade suppliers. |
